Heroes Scoop! Smallville's Lionel Luthor to Play Sylar's Dad

Lex Luthor and Sylar will soon have more in common than being TV baddies: The two will share a dad when Smallville vet John Glover arrives on Heroes as Sylar's father.

Glover has previously played Lex's dad, Lionel, but he'll be appearing sometime this spring as the man who helped bring Heroes' antihero to life, a rep for the show confirmed to TVGuide.com.

The arrival of the new father-figure will pose some challenges for Sylar, who's already had daddy issues to contend with in recent episodes. "When Sylar meets his father, he's going to see a path ahead of him that he doesn't want to take," a source tells EW's Ausiello, who first reported the casting. "He has a lot more in common with his father than he realized."

In the interim before his Heroes arrival, Glover fans can find him on ABC's Brothers & Sisters. The actor was cast this fall for an arc as Saul's (Ron Rifkin) main squeeze.

Are you ready for some Luthor-style fathering for Sylar? What kind of impact do you hope he'll have on Heroes?
